Hi everyone,
I have a big project to create a CDN (Content Delivery Network) to
replace the Akamaï job.
I have think to Squid 2.6 (debian etch package) and Apache in reverse
proxy mode (LoadBalancing and rewrite rules to specify a squid, apply
loadfactor, ...). I have a problem to evaluate the resources needed.
I have distinguish the static (image, css, js, ...) to cache (with
static.website.tld subdomain)
All static content (with ~10 websites) is above 80Go and ~10.000 hit/s.
I would start with this minimal configuration (I have omitted the
redundancy with heartbeat)

The filesystem on squid server is ReiserFS (raid 10 with hdd SAS 15K
RPM 73Go) with 4Gb ram and intel quad core.
My questions is :
- how to suppress warning message when an object is in cache more than
one day (I don't have this message this day tomorrow if you need the
exact message)?
- I should config squid with a very large cache :
cache_dir ufs /var/spool/squid 51200 256 2048
and 3Gb cache memory
for you this configuration seem's to be OK ?
Thanks in advance for your response / suggest
